Sometimes when updating packages in 0.7 I get an error like:

```julia

Are you on the beta? If so, have you tried with the nightly build instead?

Yes, using beta. I will try on the nightly on Monday. However, I would need for some package to be updated 😛

Following up, I have not been able to reproduce the error in the nightly. But I am suspicious that it is a particular package that triggers the issue, so I will keep testing.
